In
philosophy,
qualia ( or ; singular form:
quale) are individual instances of
subjective,
conscious experience. The term "qualia" derives from the
Latin neuter plural form (
qualia) of the Latin adjective meaning "of what sort" or "of what kind"). Examples of qualia include the pain of a headache, the taste of wine, or the perceived redness of an evening sky. As qualitative characters of sensation, qualia stand in contrast to "
propositional attitudes".
